摘　　要：【目的】筛选地方性优质抗烟草普通花叶病(TMV)烟草种质,为湘中北烤烟抗TMV育种提供优良的种质资源。【方法】采用苗期温室病圃人工接种诱发方法结合大田病圃鉴定,以Coker176为抗病对照、革新3号为中抗对照、G140为感病对照,对9625、金星6007、小黄金0019、401-2、小黄金1025、NGLAUCA、延烟2号等18个烤烟品种(系)进行TMV抗病性鉴定。【结果】在供试品种(系)中,筛选出抗病品种(系)2个,分别为T61和9625,占供试品种(系)总数的11.1%;中抗品种5个,分别为金星6007、03-4-3、胎里黄1061、VESTA33和云烟98,占27.8%;感病品种(系)11个,分别为小黄金0019、401-2、311、小黄金1025、NGLAUCA、延烟2号、大白筋0522、沪金3号、大叶永烟、长脖黄和NC95,占61.1%。【结论】筛选出T61和9625两个抗TMV烤烟品种,可作为湘中北地区抗TMV育种的重要种质资源;同时可在湘中北地区进行T61和9625的示范性推广种植。【Objective】The present study was conducted to select local superior tobacco varieties（lines） that were resistant to tobacco mosaic virus（TMV） in order to provide well-refined seed varieties for flue-cured tobacco resistant to TMV in central and northern part of Hunan.【 Method 】 Method of artificial inoculation and inducement in greenhouse disease nursery combined with identification in diseased field was adopted in the research.Taking Cokerl76 as disease resistance control,Gexin 3 as moderate disease resistance control,and G140 as disease susceptibility control,TMV resistance identification was conducted on 18 flue-cured tobacco varieties,such as 9625,Jinxing 6007,Xiaohuangjin 0019,401-2,Xiaohuangjin 1025,NGLAUCA,Yanyan 2,etc.【Result】In the tested varieties（lines）,two selected varieties（lines）resistant to TMV were T61 and 9625,accounted for 11.1%of total varieties;five varieties moderately resistant to TMV were Jinxing 6007,03-4-3,Tailihuang 1061,VZSTA33 and Yunyan 98,occupying 27.8%of the total varieties;eleven susceptible varieties（lines） Xiaohuangjin 0019,401-2,311.Xiaohuangjin 1025,NGLAUCA,Yanyan 2,Dabaijin 0522,Hujin 3,Dayeyongyan,Changbohuang,NC9,accounted for 61.1%of the total.【Conclusion】The selected two varieties that are resistant to TMV,T61 and 9625,are important TMV-resistant germplasm resources in central and northern part of Hunan.In addition,demonstration planting of these two varieties can be promoted in the region.
